Summer Squash and Turkey Sausage Gratin
Southerners love a casserole. They are church supper staples, great to take to the new neighbor, and equally welcome to a new mom. Cheddar, sometimes called “rat cheese” in the South, ranges in flavor from mild, nutty, and creamy to extra-sharp, rich, and robust. Gruyère is a low-moisture cow’s milk cheese from eastern France and western Switzerland. It has a sweet, rich, almost nutty flavor and is excellent for a cheese sauce. Cheddar cheese is more Southern, though, if you wanted to stay truer to those roots. Turkey sausage is much lower in fat than sausage made from pork and other kinds of meat. Use country-style or coarse-ground sausage, and if purchased in links, remove it from the casing before cooking.
